Be'iti known that I, RrcnAnn listen-- mama, a citizen of the'United States, .re

' siding at Detroit; in 'the vcounty of. Wayne scribed, pointed out in the claims and shown and State of Michigan, have invented-anew and useful Irn roveri'ient in Starting Devices for Aut'omob es, of Which-the followingl'is a specification.

In these drawings A represents the casing inclosi ng the operating mechanism of an automobile and carried in advance of the front seat and dash board A. Within the casing A is a supplemental casing B in which is arranged a gear train C, said train having at one end a pinion O and at the opposite end a pinion C The gear train is so constructed that a rotation of one-eighth upon a I part of the pinion- C, will result eight;

The pinion C is fixed uponfla shaft F having a crank portion F to which is c nnected a piston rod F carrying ha e pinion C fxed u. on the shaft G which carries a plurality o cams H. The shaft G is of course given a partial rotation corresponding to that given-to the pinion C.

Flgure l 1S3. sectional view throughithe; front portion of an automobile shovn-ng my ,charges-intothe bottomof the cylinder F :Fromthe lower end of the cylinder F leads a pipe Lwhich opens into a casing L. This ipe connects with an inlet L formed in the ottom of the ca'sirwU-whioh inlet is controlled by a check valve L-.. Thepiston rods J are connected to crank portions of a'shaft J" the outer endof which carries a gear J which meshes with a gear J carried by a shaft J The shaft J is a short stub shaft journaled, respectively, inone end of the engine casing and at the other end in the adj acent end of the casing L and carries a large gears having preferably one-half the number These'gears through the casing L and each of which carries a plurality of cams L and L", forming two sets of cams, there being in my present construction four cams in each set. cams of' each are arranged with respect to each other ninety degrees apart and they act upon the stems of spring pressed check valves L These valves are seated in the end portions of curved pipes L mounted'u on the casing L and. arranged transverse y, the ends of said pipes opening, res ectively, in alinement with the shafts L ant L. These .valves as they open and closecontrol com.-

municationbetween the said chamber and the said pipes. l'ipes M leading to the engine cylinders lead from the various pipes upon the cylinder rod and also upon a collar .0 carried by the stem. The upper end of the valve stem carries a cap 0 1n engage- Leading from the recess 0- is a small by-pass 1, the up )er end of which is normally closed by the valve Q carried at the lower end of the valve stem Q which works through an adj ustable bracket Q carried by the valve stem 0 and held normally in place by the spring R.

In order to make an operative device I have also shown in diagram in Fi 10 the circuits for the igniting system and rave also shown detail what I terma distributor, and by means of which the circuit is made and broken at the proper time. This-consists of a rotatable casing N fixed upon a shaft N which extends through the dash board A and is provided with a suitably operating handle on its rear end. A shalt N running from the'engine and suitably driven in any desired manner, as by the gear J", and the gears N 0 extends into the casing N and carries an arm N which cariies' a contact plate N 4 which is in sliding contact at all times with a metal ring N suitably insulated from the casing spaced ninety degrees apart are contact plates N which are successively engaged by the plate N as the arm N 3 is revolved. the necessary circuits are completed through the wires 1' leading from the plates N, to the sparking plugs 2, and through batter wires 3 and 5 connected, re-

spectively, to t e terminals of battery 4, and

wire 3 being connected'to the contactiingN When the engine is stopped the pistons usually stop about one-half way between the dead centers, and with the stoppage of the piston no further explosions take place in the cylinders. By means of the handle on shaft in the casing i\' can be rotated upon the shaft N thus bringing the contact plate N into contact with the plate N which is electric ally connected to the sparking plug in the cylinder in which the next explosion would have taken place if the engine had not stopped, thus at any time after stoppage of the engine resuming operation at the same point.

h In operation the pedal ii? is pressed down moving the reel; bar l and giving one eighth rotation to the pinion C and impartin eight revolutions to the pinion C The lifting ofthe iston F? sucks a charge of gas from the car ureter which upon downward movement of said piston is com ressed and forced into the valve casing L. soon as roper pressure is obtained the valve L wil lift and the gas will pass to the pipes M as the valves L are opened, and through the inlet orts O and into the recess 0 of the cvlinr er head recesses. 'Ilhe rocking of the shaft G will rock the cams H thus forcing down the valve stems O and opening the valves O" and the charge will ass into the engine cylinders and be exp odcd in the ordinary manner. If at any time the pressure in the recess 0 becomes too great, the valve Q will lift thus allowing a portion of the charge to escape. It will be obvious that upon releasing the foot pedal it will be returned to its normal position by the springs E and this will result in reverse movement of the gear train, the pinion C can rotate through a distance of one-eighth of a revolution, so that in all the valve I will lift eight times and there will be eight suction strokes and eight compressed strokes upon the part of the piston 1* for each downward pressure of the lever E. It will be noted that two valves upon opposite sides of the casing L are always held in 0 en position by the cams L and L and that t iese valves admit the Cl. arge of "as and airinto cylinders adjacent to each other, the four cylinders being arranged in sets of two each. By means of ti is arrangement as the charge is exploded in one cylinder of a set and its piston forced down a1 owing a new charge to come in, a cltarge is also being delivered to the other cylinder of the set whose piston ismaking the up stroke as the piston of the cylinder in wt ich the explosion occurred makes its down stroke.

Havin thus fully described my invention, wliat I c airn'as new and desire to secure by Letters Patent is 1. An internal combustion engine comprising gear train, means operable by the foot for driving said gear train, a combined suction and compression piston actuated by said train, engine cylinders having valves, cams rocked by the gear train, and opening said-valves, and a carbureter, the said piston drawing an explosive vapor from the carbureter and delivering the same to the engine cylinders.

2; An internal combustion engine consist-ing of engine cylinders and a carburetor, a cylinder having valve controlled communication with the carbureter and each of the engine cylinders, a piston working in the said cylinder, a gear train operating said )iston, and means operable by the foot for riving the gear train.

3. The combination in an automobile, of a gear train; foot operated means for drivii g said train; a rock shaft connected with said said cylinders, said va ves being opened by the said cams, and means also operated by the geek trainfor drawing an initial charge from the carbi lretei', and livering the same under pressure to said engine 0 linders.
